Exploring the concept of speed. Students will realise that speed is made up of two measurements, one of distance travelled, and one of time taken. These two measurements can be used to calculate speed, which can be converted to different units.
L.I. Students will be able to 1. use appropriate scales, devices & metric units for length, area, volume & capacity, weight (mass), temperature, angle and time. 2. convert between metric units, using whole numbers and commonly used decimals. 3. use a range of multiplicative strategies when operating on whole numbers.

S.C. We will
calculate speed from measured distance and time
solve multiplication problems using doubling and halving strategies
use know multiplication facts to solve multiplication problems
